John,
Thank you!! That diagram is the first time I've ever been able to locate a good picture of the CDI. I sure hope this solves my problem. I'm hoping that a new CDI will provide a constant & substantial spark to keep the fuel & oil burning. My darn plug keeps getting fouled & I'm thinking that it's because there isn't enough spark to keep things burning. I think I've ruled out about everything else. What do you think?? Sound Plausible??

This is a good site for parts. Good diagrams, but nothing that really depicts where the CDI is located. The diagram you provided looks like it is accessed from the top; raise the seat, remove the battery and the the bracket holding the battery. I'm at work now (slow day) and will post my findings later.

Success!! I had to remove the battery & the metal tray that it sits in. Then I could see the CDI attached to the back side of a bracket that holds some other electrical components. From below I had to remove the bracket that it was attached to so I could remove it from the bracket. In all it took about 10 minutes. I already ordered a new one from www.boats.net. Hopefully this will keep the spark plug sparking.
